ExtendedDismaxQParser fails to include charfilters in nostopanalyzer

In some circumstances, the ExtendedDismaxQParser tries to remove stop filters from the TokenizerChain. When building the new analyzer without the stop filters, the charfilters from the original TokenizerChain are not copied over.

The fix is trivial.

-      TokenizerChain newa = new TokenizerChain(tcq.getTokenizerFactory(), newtf);
+     TokenizerChain newa = new TokenizerChain(tcq.getCharFilterFactories(), tcq.getTokenizerFactory(), newtf);
